Question 8 of 15 $ > -11 View Policies Current Attempt in Progress A mixture of methanol (methyl alcohol) and water contains 30.00 % water by mass. Ideal Specific Gravity The specific gravity of water at 20C is about 0.9982; the specific gravity of methanol at 20C is about 0.7917. Assuming volume additivity of the components, estimate the specific gravity of the mixture at 20C.SG- What volume of this mixture is required to provide 200.0 mol of methanoli liters e Textbook and Media Save for Later Attempts: 0 of 10 used Submit Answer uestion 9 of 15 -11 This is an approximation for most liquids, unlike the exact statement that the mass of the mixture is the sum of the component masses. e Textbook and Media Save for Later Attempts: 0 of 10 used Submit Answer Example Calculation Use the correct formula to estimate the density (g/cm) at 20C of a liquid mixture containing 49.1 wt% acetone, 31.6 wt% acetic acid, and 19.3 wt% carbon tetrachloride, g/cm Physical Property Tables Save for Later Attempts: 0 of 10 used Submit Answer Question 9 of 15 - / 1 View Policies Current Attempt in Progress A liquid mixture is prepared by combining N different liquids with densities P1, P2, ... The volume of component i added to the mixture is V; and the mass fraction of this component in the mixture is xy. The components are completely miscible. Validity of Formula The following two formulas provide estimates of the density of the liquid mixture, p. If the volume of the mixture equals the sum of the pure-component volumes. Determine which one of the two formulas is correct. N p= 2x - MTP This is an approximation for most liquids, unlike the exact statement that the mass of the mixture is the sum of the component
